Code P2135 Scion Description
The P2135 code on a Scion indicates a problem with the Throttle / Pedal Position Sensor / Switch 'A' / 'B' Voltage Correlation. This means that the correlation between the voltage signals from the throttle position sensor and the pedal position sensor is not within the expected range. The throttle position sensor (TPS) and the pedal position sensor (PPS) are crucial components in the vehicle's electronic throttle control system. The TPS measures the position of the throttle valve, while the PPS detects the position of the accelerator pedal.
Common Causes of P2135 Scion
- Faulty throttle position sensor
- Faulty pedal position sensor
- Corroded or damaged wiring/connectors
- Electronic control module (ECM) issues
- Poor electrical connections
Symptoms of P2135 Scion
- Engine hesitation or stumbling
- Reduced power or acceleration
- Illuminated Check Engine Light
- Rough idle or uneven engine performance
- Vehicle going into limp mode
How to Fix P2135 Scion
- Diagnose the issue using a scan tool to retrieve the trouble codes and monitor the voltage signals from the TPS and PPS.
- Inspect the wiring and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as needed.
- Test the throttle position sensor and pedal position sensor using a multimeter to ensure they are functioning correctly. Replace any faulty sensors.
- Clear the trouble codes and perform a test drive to verify that the issue has been resolved.
- If the problem persists, further diagnostic steps may be necessary, such as testing the ECM or performing a relearn procedure for the throttle control system.
Cost to Fix P2135 Scion
The typical repair costs for addressing a P2135 code on a Scion can range from $200 to $500, including parts and labor. However, it's essential to keep in mind that specific diagnosis time and labor rates at auto repair shops can vary widely. Factors such as the vehicle's make and model, engine type, and location can all influence the final repair costs. It's advisable to obtain quotes from multiple shops to ensure you get the best deal for your specific situation.

Frequently Asked Questions about P2135 Scion Code
1. What does the OBDII code P2135 mean for a Scion?
P2135 indicates a voltage correlation issue between throttle position sensor 'A' and 'B', which could affect throttle control.
2. What are the common symptoms of code P2135 in a Scion?
Symptoms include reduced engine power, poor acceleration, hesitation, and activation of "limp mode."
3. What causes the P2135 code to occur in a Scion?
Common causes include faulty throttle position sensors, damaged wiring, corrosion in connectors, or a failing throttle body.
4. Can I drive my Scion with the P2135 code?
Driving with code P2135 is not recommended, as the vehicle may enter limp mode or experience sudden loss of power.
5. How do you diagnose the P2135 code in a Scion?
Diagnosis involves scanning for codes, inspecting the throttle position sensors, checking wiring and connectors, and testing the throttle body.
6. How do you fix the P2135 code on a Scion?
Repairs may include replacing the throttle position sensor, repairing damaged wiring, cleaning connectors, or replacing the throttle body.
7. Does the P2135 code always mean the throttle position sensor is bad?
No, it could also be due to wiring issues, connector corrosion, or problems with the throttle body.
8. How much does it cost to fix the P2135 code on a Scion?
Repair costs vary but typically range from $100 to $600, depending on whether the sensor, wiring, or throttle body needs replacement.
9. Can a dirty throttle body cause the P2135 code?
Yes, a dirty or sticking throttle body can disrupt sensor readings and trigger the code.
10. Will clearing the P2135 code fix the problem in a Scion?
Clearing the code may temporarily erase it, but the underlying issue must be resolved to prevent it from returning.
